Funny Story About Fragments

Sometimes funny things happen in Obertopia.  Rarely are they planned.  The story you are about to read is just one example.

I was trying to explain to my 4th period today what a sentence fragment was... and I was trying to come up with something off the top of my head.  Here's what came out: 

"Okay guys, here's another example of a fragment: 'So that's when my hair got stuck in the toilet.'" 

 Seriously-this really happened! They all started laughing, as did I. Then one kid asked, 

"Uhm, how did your hair get stuck in the toilet?"
